Just in time for the festive season, the tiny record measures a ridiculously small 40 micrometers in diameter.
Created by a team of researchers at DTU Physics, the record contains around 40 seconds of the popular Christmas song Rocking Around the Christmas Tree
It was made using a new nano-sculpting machine - the Nanofrazor - which is capable of engraving patterns into surfaces at resolutions much smaller than anything that has come before.
"I have done lithography for 30 years, and although we've had this machine for a while, it still feels like science fiction," said Professor Peter Boggild.
"We've done many experiments, like making a copy of the Mona Lisa in a 12 by 16-micrometer area with a pixel size of ten nanometers. We've also printed an image of DTU's founder - Hans Christian Orsted—in an 8 by 12-micrometer size with a pixel size of 2,540,000 DPI."
"To get an idea of the scale we are working at, we could write our signatures on a red blood cell with this thing."
"The most radical thing is that we can create free-form 3D landscapes at that crazy resolution - this gray-scale nanolithography is a true game-changer for our research."
